Abstract
The invention is a corner rack with one front face that has teeth. A corner rack is a linear gear interface that can be placed in corners, such that the teeth face out from the corner at an angle, rather than running parallel with the walls. The teeth of the corner rack have a profile that can engage with the profile of a silent chain. The combination of the corner rack and silent chain allows an attached motor to be distanced from the corner rack, so that a lifting device driven by the corner rack and silent chain can be placed in and utilized in corners. This leads to increased versatility and efficiency.
Claims16
A transmission system comprising:
- a silent chain having a first row of link plate and a second row of link plate, each link plate in the first row of link plates comprising first link plate teeth and each link pate in the second row of link plates comprising second link plate teeth, wherein the first link plate teeth and the second link plate teeth having different shape profile with repect to each other;
- a corner rack, the corner rack comprising a front face, the front face comprising teeth, the teeth comprising a profile that engages with the silent chain;
- a set of gears that bends the silent chain as the silent chain enters the teeth of the corner rack, that draws the chain straight to engage the first link plate teeth and the second link plate teeth with the teeth of the corner rack, and that bends the silent chain as the silent chain exits the teeth of the corner rack,
- wherein the first link plate teeth and the second link plate teeth are longitudinally offset with respect to each other when the silent chain is strenghtened, and
- wherein a tooth of the first link plate teeth and a tooth of the second link plate teeth are longitudinally aligned with respect to each other at a bend as the silent chain is bent by the set of gears.
